A comparison between single seed descent and early cross selection in wheat breeding. II: The evaluative generations
Two selection procedures in wheat breeding were compared on the basis of their ability to supply high yielding inbred lines. The first procedure consists of an early selection between crosses in the F sub(3) generation, based on cross performance. In the second procedure selection is postponed until...

description | Two selection procedures in wheat breeding were compared on the basis of their ability to supply high yielding inbred lines. The first procedure consists of an early selection between crosses in the F sub(3) generation, based on cross performance. In the second procedure selection is postponed until the F sub(6), which is derived by single seed descent. The two procedures are evaluated in a two year test, using pseudo-lines of spring wheat. These pseudo-lines consist of mixtures of varieties and enable an estimation of the true genetic parameters. In this way the accuracy of the predictions can be examined. This paper gives the final results after the second year. From the first year it was found that the F sub(3) cross predictions were very inaccurate, whereas selection in the SSD-F sub(6) appeared to perform well. This resulted in a higher yielding set of lines evolving from the SSD-F sub(6). Despite a pronounced genotype-year interaction this difference in yield level was also found between the F sub(7) and the F sub(6) lines, derived from the selected crosses in the F sub(3). We conclude that the early selection procedure is not advantageous compared to the fast SSD procedure. |
